Application tiled September 22, 1913. Serial No. 791,040.

To all ulmril it may concer-n Be it known that I, ALBERT H. SIssoN,

a citizen of the United States, residing at High Point, in the county of Guilford and State of North Carolina, have invented certain new and 'useful Improvements in Sashl Construction, of which the following 1s a specification.

This invention while relating to sash construction in general has for its particular object the formation of the sashcorner', lock relation that. they cooperate. in effecting a compact rigid construction of which the sash members may be much narrower .than is ordinarily found to benecessary to accommodate the lock and'of lightermaterial due to the reinforcing action .of the lock plate. The lock plate also serves as a housing for the locking elements and has formed integral therewith the sash lift. Moreover, the engagement of the lock with the window operates to normally thrust the sash therefrom and maintain vthe same under spring:

tension againstfl the opposite guide to pre-I vent rattling and Amore effectively exclude the element Other advantages from the'standpoint of mechanical construction and operatipn \vill be apparent to :those skilled in this art In order thatfthe invention may be readily understood-two practical embodiments of the same are set forth in the accompanying drawings. and in the description based thereon. As the invention is alscapable of embodiment in other and varied constructional forms the drawings and description are to be construed as illustrative and notin an unnecessarily limiting sense.

In tlrofdrawings: Figure 1 `1s a front elevation o one form of sash cornervshown 1n assembled relation to the window frame' which is partially broken away Fig. 2 is a horizontal section taken on the line 2--2 of Fig. 1; Fig. 3 is a vertical section on the line 3e3 of Fig. 2; Fig. 4 is a vertical section on the line 1 -4 of Fig. 2; Fig. 5 is a viewsimilar to Fig. 1-showinganother form of construction; Fig. 6 is a vertical section through the sash-'looking toward the lock'; Fig. 7 is ahorizontal-section on the line 7*7 of Fig. 5; and Fig. 8 is a vertical section on the line 8 8 of Fig. 5.

Having reference particularly to Figs. 1 to 4 inclusive the sash members, that is to cessity of 'material for the same.

say the rail 1l and stile 12 are shown as mitered at 13 and connected to form a sash corner. The sash members 11 and 12 are here shown as formed of sheet metal tubular 1n cross section having a rentrant portionA 14 forming a groove for the reception of glass 15 with suitable interposed packing 16. It is desirable both from the standpoint of economy of material and also to encroach as l1ttle as possible upon the window opening that the rail and stile be as narrow as 1s consistent with strengthand with the nebearing for the sash lock. sash members are made wider than would be otherwise necessary for the lreason that one, and usually the rail, must. be made wide enough to accommodate the lock plate and lock. By the present invention I am enabled to reduce the width of the rail and stile' to an inch or less and also to employ lighter In carrying out the invention I provide .a lock plate 17 which is secured to the rail and stile. advantageously by screws 1S extending through into an interior corner reinforcement hereafter described. The lock plate is angular in outline and preferably L- shaped. one leg extendingT longitudinally of each of the sash members for a considerable distance beyond the corner of the sash thus bridging the mitered joint bers. The'inner edges of fieeted the plate are delaterallv toward the glass as .indicated at 19 and fit snugly against the inner i edges of bot-h the rail and stile. The horizontal leg of the plate also preferably extends upwardly and inwardly beyond the rail as-indieated at 20 and constitutes a housing for the bolt 21 of the lock, the

finger piece v22 of which projects through the plate extension 20. The inner edge of the extension 20 is substantiallv vertical and in line with the outer wall of the glazing groove so as to lie closely adjacent the outer face of the glass while the sash lift 23, formed integral with the plate, projects outwardly in a substantially horizontal direction. It will be observed that the outer edges of the lock plate 17 do not extend to the out-er edges of the rail and stile but are suflieiently remote therefrom to clear the Stop 24 and the sill 25 thus present-ing for engagement with the stop and sill a plane surface throughout and not requiring the affording a proper support andA Ordinarily the between the memtion shown o in port n portion .the sash members by the pluto, this forni of bolt zicl'iiiiting spring being old sind null linoivii and for that reuF "llie tension of the spring is sullicient, to prees the end of the latch l strongly iiguinst the plate 30 und thus force the sash in the opposite direction against. the stop to prei-'ent rattling and more eilectively exclude nir dust and moisture,

The snug son 'iiot illustrated,

tit of the deflected portions t9 of thel lock plate over the inner edges of the siifsli members, iis Ailse the snug tit of the bolt 2l iiitbin the receiss 32 of the stile of themselves tend to eilect e. irni engagement of the parte, thus materially assisting iin relieving the screws, i8 from undue strain. his result. is iii-ther enhanced by the proion of e id 33 projecting forwardly trom the loci; 'plate into engagement with en aperture in the 'fece of the stile.

ll'liiving; reference to the forni of constructo 8 inclusive, here the rail Mend the :tile are likewise connect'- ed by' mitered joint 1&3 and the lock plate el is also of L construction and entends or si considerable distance lioriiiontally and vertically from tlie joint along the sash members. l

Both of the eleteiire sinn: liiily dellec'ted inwardly, iis/s own 45o', to lit snugly over-the. inner edges oi tbe stile and .rail sind :i5 :in additional point ot eupil o' the plaie is eent- 'inbeyond the edge of the. poro the plete. flinto en gagenient with in etiect. a

ln order to provide a particularly rigid and efficient connection between the rail and stile at each corner of the sash a reinforcing lining 64 is provided which is Lfshaped in side elevation and substantially U-shii ed in cross section, the U opening inwardly. The limbs of the U are curved inwrrdly at their extremities, es indicated ai; 65 so as to follow the 'inward clirvatiire of the sash members into the restricted space at lcti-cli side of the glazing groove and ten-niente with their edges abutting nguiiisa, the wells of siiifl groove es clearly sliown in the draw ingn Heretetore it has not been iisiiiil to: have the reinforcement extend into this space on cach side of the glazing groove and tbe lateral strength of the reinforcement has been correspondingly limited.

As shown. in Fig l, the recess 320i .the stilewitliin which is accommodated the locking bolt 2l sind its angular-portion 26, also extends through the reinforcing lining 64;. nt reason of tlio intiirned edge 65 of he letter the slot dees not extend entirely to the edge and 'the weakening eFect of the slot upon tbe stile is ilereforemucli reduced.

"Eber portion of the reinforcement which extends into the lower rail is slottedv es indicated in Fig. so as to embrace the dove-tail groove GOand the slide 61 the relative. position o the two walls. oA thev eiiiforeeinent beiiigimziintaincl by ii spacing bolt 66 extendingtransversely and rig idly joining the. tw walls.
